2 divisions of the n s

Peripheral Nervous System (branching out, toward the sides)

nerves

Central Nervous System

Brain

Spinal Cord

2 Divisions of the N.S.


Nervous system

3 Parts:

Brain

Cerebrum (thinking, reasoning, sensing)

Cerebellum (routine motion, muscle coordination)

Brain stem & medulla (involuntary actions: breathing, heart beat)

Spinal cord

Brings messages to and from the brain, travels through the vertebrae for protection

If severed you are paralyzed from there down

Nerves

Motor Neurons (brain  muscles to move)

Interneurons (from one neuron to another)

Sensory Neurons (body  brain to sense: touch, smell, sound, taste, sight)

One nerve cell = neuron, many neurons = nerve

Nervous System



Endocrine system
Endocrine System

  • Signals are hormonesthat travel through the blood

    Ex: growth hormone, adrenaline

  • They fit like a lock and key with targetcells in the organ they will affect

  • Mmostact slowly over a long period of time

  • Glandsproduce hormones

    • Pituitary is the master gland

  • Hypothalamus in brain connects the Nervous and Endocrine Systems


  • Immune system
    Immune System

    • Fights pathogens due to foreign antigens

      Bacteria, viruses, fungus

    • First line of defense = barriers

      • Skin*, saliva, tears

      • Nose hairs, mucus

    • Second line of defense=white blood cells

      • Macrophages “eat” pathogens

      • WBCs can produce antibodies to kill pathogens
